Great fun Mike !
A while ago a chap in Essex was trying to recreate Supervan. The original one long gone, (as far as we know). I haven't heard any updates lately though.
Supervan 3, which we have in the Ford Heritage Collection at Dagenham, is a mongrel. It's actually Supervan 2 (a MK2) rehashed to resemble a '95' Transit.
It's a shame, the one you'd really want is the missing one !
